Number 1 - usually a person has a relative/kid/friend that does MA training.
Convo as follows

Me: Yeah I do a bit of martial arts
woman:Really? my brother and son do martial arts :). They do something called Ninja aikido or something?

Me:Nevermind I just play Soccer

Number 2 - This involves a person who gets you into trouble with Ego ... convo unfortunately goes as follows:

Strange man: I heard you do MMA! is that true
Me: Amatuer MMA from time to time.
Friend: He can kick your ass!
Me:...*face palm*
Strange man: What would you do if I do *THIS!* (sometimes they deliberatly touch you and do something rude - rare occassion)
Me:Alright lemme show you a cool BJJ move!
Strange man: Jiu Jitsu? I just wan't to know how to knock some one out

Number 3 - This involved meeting a lady -

Attractive Lady: So what do you do for a living?
Me: I do MMA, ya know like the UFC stuff, strikeforce, etc.
Attractive Lady: *takes panties off*

Number 4! - I just tell people I play soccer and love to do crossfit :)

(My body is built pretty nice and I am constantly asked if I play sports)

As the judoka progresses, he will learn to handle extreme physical exertion and suffering, but there is one thing that will push his endurance to its very limits. This occurs in social encounters with friends from the during a lull in the conversation, suddenly flatten their palms and do some weird movements while asking, ĎAre you still doing the old . . . karate?

One of my favourite bits of the Pyjama Game it always comes to mind when one of my supposedly close friend can't remember the four letter which make up the sport which has physically and mental tortured me for the previous week while they have been posting picture of their cat on facebook

"This is my friend. He does martial arts. He's a ninja/he can beat you/20 guys up." this is pretty dangerous. If someone suggests this, it probably means they just want you around so they can start ****.

Good god, I hate this one. One of my friends insists on telling people how "dangerous" I am. I can pick my own fights, thanks.

The nice thing about muay thai is that you typically only get two types of responses. The first, and by far the most common, is people who have no idea what it is, the "What, mai tai, isn't that a drink?" crowd. The much smaller group is people already familiar with combat sports who actually know what I'm talking about.
